Suggested by [Numerical Analysis in Tcl]; how to implement numerical statements such as a=b*c. I have removed my own prodding code which has satisfactorily produced some good responses to show implementations that already exist such as [Gadgets].

[slebetman] Notwithstanding the fact that a '''real number''' in mathematics means something completely different (see [Computers and real numbers]) I've implemented this concept a bit more intuitively (and if you consider lines of code, also more ''simply''). Unlike the implementation (removed by original author), my '''var'''iables exist as both variables and commands. Personally I would call it a [C-like syntax for numbers]:

[GWM] yes real numbers in maths are different but as this is a numerical analysis related item, real means whatever a compiled computer program uses as a real (especially the C language) - as used in numerical analysis. I agree that '''C-like syntax''' is a more appropriate term. I like this implementation by slebetman as it is simple, and allows local variables and recursion.

[slebetman] Since we're in agreement, I've moved my implementation to [C-like syntax for numbers].
